Beschreibung:
Forests are a substantial terrestrial carbon sink, but anthropogenic changes in land
\nuse and climate have considerably reduced the scale of this system1
\n. Remote-sensing
\nestimates to quantify carbon losses from global forests2\xe2\x80\x935
\n are characterized by
\nconsiderable uncertainty and we lack a comprehensive ground-sourced evaluation to
\nbenchmark these estimates. Here we combine several ground-sourced6
\n and satellitederived approaches2,7,8
\n to evaluate the scale of the global forest carbon potential
\noutside agricultural and urban lands. Despite regional variation, the predictions
\ndemonstrated remarkable consistency at a global scale, with only a 12% diference
\nbetween the ground-sourced and satellite-derived estimates. At present, global forest
\ncarbon storage is markedly under the natural potential, with a total defcit of 226\xe2\x80\x89Gt
\n(model range\xe2\x80\x89=\xe2\x80\x89151\xe2\x80\x93363\xe2\x80\x89Gt) in areas with low human footprint. Most (61%, 139\xe2\x80\x89Gt\xe2\x80\x89C)
\nof this potential is in areas with existing forests, in which ecosystem protection can
\nallow forests to recover to maturity. The remaining 39% (87\xe2\x80\x89Gt\xe2\x80\x89C) of potential lies in
\nregions in which forests have been removed or fragmented. Although forests cannot
\nbe a substitute for emissions reductions, our results support the idea2,3,9
\n that the
\nconservation, restoration and sustainable management of diverse forests ofer
\nvaluable contributions to meeting global climate and biodiversity targets.
